ALSA: pcm: Replace sprintf() with sysfs_emit()
For sysfs outputs, it's safer to use a new helper, sysfs_emit(), instead of the raw sprintf() & co. This patch replaces such a sprintf() call straightforwardly with the new helper. Link: https://lore.kernel.org/r/20220801165639.26030-6-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
